'Patent 310,692,610, dated February 4, 1902. 30,960. Divided and this application lod September 20, 1901. Serial No. 75,814. (No model.)

To 2l/ZJ; whom if: may concern: l Beit known that 1, FRANK A. BROWNELL, of Rochester, in the county of Monroe and State of New York, have invented certain new 5 and useful Improve-ments in Focusing Devices for Photographic Cameras; and 1 do hereby declare the following to be a full,clear, and exact description of the saine, reference being had to the accompanying drawings, io forming a part of this specification, and to the reference-iiurnerals marked thereon. l (My present invention relates to photographic cameras, and has for its object particularly to provide an improvedv bed or support for the lens-carriage and means for focusing or causing, the relative adjustments of the-lens and sensitized iilm or plate, whereby the lens-support may be moved outward quite a distance and locked and secured iirmly zo when a lens ol extra long focus is employed and whereby also the approximate and fineijv focusing adjustments may be quickly and i(ic-i curately accomplished.

The invention is particularly applicable to' folding cameras-such, for instance, as

shown in iny former application, Serial No.

- 30,960, filed September 24, 1900, of which this toward the i'earvof the camera.

the focusing-Screen of `ground glass is a division-the said parts being so conls tructed that iliec'aniei'a maybe ioldd or 3o collapsed into small compass.

A further object of my invention is to provide vertical and lateral adjustments for the lens by means of whichhtlie operator may easily shift it laterally and vertically from its 35 central or normal position and automatically secure it and also to provide a hood or screen for the focusing-surface which shall be contained within the camera and adapted to obviate the use of the usual-focusing-cloth. 4o Toiiiese and other ends the invention consists in certain improvements in construction and combinations of parts, all as will be hereinateifully described, the novelfeatures being pointed out in the claims at the end of this specification.

Similar reference-numerals in the sever-al figures indicate similar parts.

The camera forming the subjectfniatter of my present invention is adapted to be folded into small compass with the operating parts all inclosed, so that it may be readily carried by the operator, and to this end the camerabody proper embodieslan open-frame oi casing l, to the lower front edge of 'which is hinged a lidy or door 2 and to the rear side is applied an open traine .3, carrying at its rear 3X and connected to theiranie 1 at the sides in such manner that it may be adjusted rearwardly and turned or tilted with relation to the frame 1 and operate as a tilting swing-back` for maintaining in vertical position the plate or film when the frontot' the camera and lens is elevated or depressed, a foi-iii of mechanism for this purpose being shown in the parent application before referred to. -Tiie lid or door 2 is preferably'lormed of. sheet metal, having the side and end flanges f1 adapted to fit within the front edge of the frame 1 and having its rear edge turned over to forni a hinge member, through which extends the pintle or rod 5, also operating in suitable ears. in a plate G, secured to the lower side of the frame 1. The dimensions of the lid or door are suoli that it will fit snugly within the' front of the traine 1 aiidmay be fastened with its outer surface iiusli with the trame by means ot a suitable spring-catch, sucii as 7, adapted to engage a suitable projection ar ranged upon said lid. The door 2 is provided Awith an aperture in'its outer face and upon its inner face with a nut or threaded socket 8, adapted to receive the screw of a tripodllead.

9' indicates suitable links pivoted to theV door2 and slotted for thev accommodation of the Shanks of the headed pins 10, secured to," the inner side of the frame 1, said links be?j ing provided with springs 11, which coperate' with th'e pins 10 and force the links vertically, so that the lateral slotsin the ends will engage the pins and normally hold the door at right yangles, as shown in Fig. 1.

In ther present embodiment of my invention the door 2 constitutes a camera-bedA on which the adjustable or foc n sing'parts of the the flanges 13, said shaft orarbor having upon its outer end a longitudinally-adjustable sleeve provided with a milledl head 18 and with a slot inv which operates a screw 19,v secured to the arbor so that it may be adjusted longitudinally of the latter, but turn with it, a small-friction-spring 20 beingarranged be,- tween the arbor and sleeve to prevent accidental movement. (See Fig. '2.)

21 indicates a tubular-locking-screw screwn ingin a nut 22 at its inner end and operating upon one ofthe flanges 13 to 'clamp the latter upon the section 14 and secure itin adjusted position, said clamping 1 screw having the milled head 23, as.` showt. .'in Figs. 2 and 5. Both the milled heads 18 and 23 are located in a recess formed at one side 'of the door, so as to permit the latter to be closed within the framela .j ,3., l

To the inner side of the door 2 are fastened wooden strips 25, serving to cover and 'protect the flanges 13 ofthe Way-plate 14andtostiffen the parts. Q1

Secured to the upper side of the section 14 is a plate havin-g vertical ly-extending grooved flanges 26, the grooves forming ways in which operate the edges of a longitudinally-adjust able plate or slide 27, having vsecured to its 'upper side a way-plate 28, upon which latter slides tlie block or carriage constituting'the lens-support, This carriage in the present instance embodies the metal frame v0r casing ,l 29, having the dependingr flangesgprovided with grooves for the reception ofthe edges of the plate 28, and the frame or carriage' is adapted to be adj nlstably securedl to the plate .2S by suitable devices hereinafter described.

Located in the bottom of the' frame 1 is a bracketBO, having at its upper side flanges 31', whichrwhen the door2is opened'extends in line with theftxedges of way-plate 28, so that the carriagelerrying the lens-support may l' slidefrom the plate 28 upon said flanges,

eaeic which theieforeconstitutea continuation of the ways for the lens-support when it is desired to fold up the door and close the camera.

It will be noted that the lens-support is adjustable upon the way-plate 28, the slide carrying the latter is adjustable upon the section 14', 'and the latter upon the flange-plates 13, secured to the door or support 2, and that therefore the lens may be adjusted outwardly A approximately three times` the length of the door 2; but `in order to prevent the outward movement of the way-plate 28 until the lens carriage or support is moved outward toits extreme outer end and also to insure the extreme inward movement of the plate 28 before or whenthe lens-support is moved onto the ways 31 within the frame l when the camera is -to be closed I provide catches between the slide carrying the plate 2S and the section 14 on the `door 2 and also between the wayplate 28 and the lensv carriage or frame and a locking-or fastening device between the section 14 and the ways 13, as will be described. In carrying out thisportion of the invention I provide the edge 'of the slide 27 near the forward portion with a small slot 3l, through .which is adapted to extend the end of a spring- 'catch 36, secured t0 the section 14, when the slide 27 is in the rearmostvposition, the upper end of said spring-catch projecting upward far enough to' be engaged by the lower edge of the flange on the plateupon the lens-carriage 29, so that whilesaid catch normally holds the slide 27 when the lens-carriage is moved outward the flange of the carriage 29 will engage with and depress the catch, allowing said slide 27 to be carried outward by the carriage, the forward end of which engages with a downwardly-extending flange32, formed on the end of` the plate 28, las shown in Fig. 1. At the rear end of the slide 27 is provided an opening- 131, similar to 3l, with which the catch-36 vengages when the slide is drawn to its extreme outward position, so that the latter is locked to the section 14 until the flange 'on the carriage again engages the catch 36 'and-releases it from the aperture 131 upon the inward movement ot' the lens-carriage.

At the rear end, of the slide 27, upon the under side thereof, vis arranged a catch 33,

pivoted at 34 and provided with a sprin'g 35,v

all as shown in Fig. 5, said spring operating normally to throw the pointed end of the catch forward through an opening in the slide 27 and into the pathof the flange or projection on the lens-carriage 29. The catch is also provided With'an extension adapted to engage a stationary pinor projection 13G, se-

IIO

cured tothe door or bed 2, the relation of the y parts' being such that when the slide 27 is drawn outward the extension of the catch 33, being removed from the stop or pin 136, will permit theA spring to throw the end ot the catch outward into the path of the projectionor flange on the lens-carriage, s Q that as said lens-carriage is moved backward to return the lens-support t'o the casing the slide 27 will be ycarried lby it until the catch is tripped byengagement with the stop v136, when the catch will be withdrawn and the lenscarriage can move upon the supplemental ways or guides within the frame or casing 1.

lWhen the camera is used `with ordinary short-focus lenses, the carriage `29 need not be moved outwardly far enough to disengage the catch 36, and the fine focusing adjustment may be accomplished by loosening the clamping-screw-21 and manipulating the arbor 17, in which case the section 14 and slide 27 i are locked and moved together. If a greater movement of the lens-carriage 29 than that describedis required for the coarse adj ustment, the latter is moved' outward to the end of the slide 27,- disengagin g catch 36 from` its forward end and carrying said slideoutwardwith it as far as desired. 1f the outward vmovement is sufficient to draw the slide 27so that the catch 36 engages the recess 131, the section 14 and slide 27 are locked rigidly together and the fine adjustment may be accomplished by the arbor 17, as before. In both the .instances described the ne adjustment may be accomplished bythe arbor 17 while the slide 27 and section 14 are locked together by the catch 36, with the slide 27 either extended or retracted, as will be understood.

The slide is movable upon the way on the section-14, whichy latter constitutes a support for the slide, and while it may be maintained stationary it is also adjustable upon the guides on the bed or door either for an accurate adjustment or to provide an extended base when desired, or both.

The'bracket 30, having the supplemental ways, isslotted or recessed in its upper side, as at 30X, so that when the door or bed' is closed against the frame 1 the inner ends of the way-plates maylnot interfere with the track-slides 14 and 27, which latter are raised somewhat above the bottom ot' the frame, as are also the upper portions of the bracket 30.

The lens of the camera is mounted in a suitable frame 40, either with a shutter of any suitable construction, as shown, or without, said frame being provided at the. side with vertically-perforated ears 41, two on each side,

through which extend supporting-standards 42, fastened at their lower ends by socket.

pieces 43 and nuts 44 to the end of a transversely-extending plate 45, having at the rear a ange 46, extending over the rear end ol the plate' ,29, constituting the carriage, andv v nally-extending slot 4S, through which passes the shank ot a pin 49,'said pin having uponL its upper end a head 50, provided with a transverse cam groove or notch and also provided with a threaded portion 51, upon which is securedan adjustable nut 52, arranged beneath the plate constituting the carriage 29, said pin extending below the nut and serv-ing as the centering device for the carriage-clamping mechanism, as will be described.

53 indicates a washer-plate on top of the frame 45 and prevented from turning thereon by flanges, as shown, and 54 a cam-plate encircling the stud or pin 49,having a cam projection cooperating with the cam-recesses in the under side .of the head 50, and having an upwardly-extending arm engaging in a slot 55 in a thumb-lever 56, pivoted at 57, and having the operating'portion 58 arranged near one of the standards 42. f

. 59 indicates a spring secured'to a standard and engaging the lever 56 and moving it in a direction to turn the cam-plate 54 and canse it to bind the plate 45 and secure the latter to the plate or frame 29, as will be understood.

In order to provide for the vertical adjustment of the lens-frame 40 upon the standards 42, I .provide the latter with a series of annular notches 65 near-their upper ends, with the inner sides of which cooperate projections or shoulders 66, formed upon spring-arms 67, secured to the sides of the lens-frame, the

. extreme ends of said spring-arms extending outward around the standards, as shown at 68, to form grasping portions, by means of which the operator may compress the portions 68 between his fingers and raise or lower the lens-frame and allow it to be secured by the engagement of the spring-catches. To insure the lens being left in normal or central position, I provide upon the standards 42 grooves 69, with which cooperate the lower free ends of the spring-arms 67, these serving .as centering devices, as will be understood.

62 indicates spring-arms, formed preferably.

of a single piece of spring-wire, operating upon the pins 61 to move them outward and turn the cam-levers 60 upon the pivot in such manner that the cam projections will extend across each other and move a clamp-block 63, arranged beneath them, down into contact with the upper side of the way-plate 28,thereby locking the latter and the carriage 29 firmly together. To cause the release of said carriage from its way and the longitudinal adj ustment thereof in the manner described, the operator grasps and presses inward the thumb- TOO IIC

pieces 6l and moves the carriage in or out, the connections described preventing it from slipping from the Way-plates.

At the rear of the open frame 3 is provided a frame 70, carrying the usual focusing-screen of ground glass or similar material, (indicated by 3X,) and in order to obviate the necessity of employing a removable focusing-cloth I provide at the rear of the frame a door or lid 7l, hinged at the upper edge and provided With a lug operated upon by a wing or leaf spring 72, (see Figs. l and 9,) adapted to normally maintain said door or lid elevated to permit the examination of the image upon the ground glass. At the sides of this door are triangular flexible wings 73, connected to the door-frame and serving not only to limit the opening movement of the door, caused by the spring, but to shade the ground glass at the side and form a shade or hood, so that the image may be visible to the operator. These wings or sides fold between the door and ground glass when the former is closed, and the door is maintained normally closed against the tension of the spring by a small movable catch-plate 74. In order, therefore, to inspect the ground glass for focusing, it is only necessary for the operator to release the catch, when the door will fly open to the position shown in Fig. 8.

The particular construction of the swingback and its adjusting mechanism is not claimed nor fully shown herein, but is retained in my pending application of which this is a division.
